Answer:
P(success)=0.2 matches the probability histogram.
Step-by-step explanation:
Formula : 
Where X represents the number of successes.
p represents probability of success .
1-p represents probability of failure.
Now when X= 0 the probability is 0.64 (Using histogram )
So, 
So, the probability of success = 0.2
Hence P(success)=0.2 matches the probability histogram.
